The first measurement of the branching ratio of the ultra-rare K+→π+νν¯ decay and the searches for production of feebly interacting particles predicted by dark scalar models from the NA62 experiment at CERN are presented. The results of a search for in-flight decays of dark photon to ℓ+ℓ− pairs with data collected in beam-dump mode in 2021 are also reported.

Abstract
The first measurement of the branching ratio of the ultra-rare K+→π+νν¯ decay and the searches for production of feebly interacting particles predicted by dark scalar models from the NA62 experiment at CERN are presented. The results of a search for in-flight decays of dark photon to ℓ+ℓ− pairs with data collected in beam-dump mode in 2021 are also reported.File in questo prodotto:
